The report obtained by Radar was written by authorities after searching the Los Olivos estate in 2003, as part of the continuing child sex abuse investigation.

'The documents collected by the Santa Barbara County Sheriff’s Department paint a dark and frightening picture of Jackson,' an investigator told Radar.

'The documents exposed Jackson as a manipulative, drug-and-sex-crazed predator who used blood, gore, sexually explicit images of animal sacrifice and perverse adult sex acts to bend children to his will,' the source said.

However, Kelly Hoover, a spokeswoman for the Santa Barbara Sheriff’s Office, told The LA Times, 'Some of the documents appear to be copies of reports that were authored by Sheriff's Office personnel as well as evidentiary photographs taken by Sheriff's Office personnel interspersed with content that appears to be obtained off the internet or through unknown sources."

Jackson’s daughter, Paris Jackson, has defended her dad on social media.

'Unfortunately negativity will always sell. I urge you all to ignore the trash & the parasites who make a career trying to slander my father,' she wrote on Twitter.

'The most pure people are always torn down.. It will continue to be proven that my beloved dad has always been and forever will be innocent.'

The estate of Michael Jackson released the following statement.

'Seven years ago this coming Saturday, the world lost an amazing artist and humanitarian devoted to helping children in need in all corners of the world. Michael Jackson's fans, including the Executors of his estate, prefer to remember the wonderful gifts Michael left behind instead of having to once again see his good name dragged through the mud by tabloid trash.

Everything in these reports, including what the County of Santa Barbara calls "content that appears to be obtained off the Internet or through unknown sources" is false, no doubt timed to the anniversary of Michael's passing. Those who continue to shamelessly exploit Michael via sleazy internet "click bait" ignore that he was acquitted by a jury in 2005 on every one of the 14 salacious charges brought against him in a failed witch hunt.

Michael remains just as innocent of these smears in death as he was in life even though he isn't here to defend himself. Enough is enough.'
